Chrysanthemum plant named ‘Zanmublush’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmublush’ characterized by its medium sized blooms with dark red ray florets and prolific branching; natural season flowering date September 21; blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmublush’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmublush’ is of the botanical classificationChrysanthemum×morifolium Ramat.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmublush’. ‘Zanmublush’ is a product ofa breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around September 21,blooming for a period of 5 weeks. ‘Zanmublush’ is a seedling resultingfrom a cross of the female parent 36787 (unpatented) with the maleparent 33503 (unpatented). Plants of the new cultivar ‘Zanmublush’differ from plants of the female parent in the following characteristic.(1) Natural season flowering date—Plants of the seedling flower one weeklater than those of the female parent. Plants of the new cultivar‘Zanmublush’ differ from plants of the male parent in the followingcharacteristics. (1) Natural season flowering date—Plants of theseedling flower about two weeks earlier than those of the male parent.(2) Inflorescence size—Blooms of the seedling are larger than those ofthe male parent.

The new and distinct cultivar was discovered and selected as a floweringplant by Henricus Cornelius Maria Jacobs on a cultivated field inRijsenhout, The Netherlands in May 2011. The first act of asexualproduction of ‘Zanmublush’ was accomplished in July 2011 when vegetativecuttings from the initial selection were propagated further in acontrolled environment in Rijsenhout, the Netherlands. In summer, about6-8 days are needed to initiate roots in cuttings of the new cultivar,after another 5 days rooted plants are formed. The new cultivar has beenfound to retain its distinctive characteristics through successivepropagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (ofabout 18 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants in theperiod of 16 to 21 weeks of age grown outdoor in Rijsenhout, theNetherlands, under natural day length and temperature and planted inweek 23 in 2015, receiving drip irrigation. The natural blooming date ofthis crop was September 21 (week 39). The average height of the plantswas 30 cm. No growth retardants were used. No tests were done on diseaseor insect resistance or susceptibility. No tests were done on cold ordrought tolerance. This new variety produces medium sized blooms withdark red ray florets blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existingcultivar in comparison to ‘Zanmublush’ is ‘Zanmuhots’ (U.S. Plant patentapplication Ser. No. 13/998,972.). When ‘Zanmuhots’ and ‘Zanmublush’ arebeing compared the following difference is noticed: The differences of‘Zanmuhots’ and ‘Zanmublush’ are (1). Natural season flowering date. And(2). Plant vigor. (1). Plants of ‘Zanmublush’ flower later in the seasonthan plants of ‘Zanmuhots’. (2). Plants of ‘Zanmublush’ are lessvigorous than plants of ‘Zanmuhots’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmublush’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
